The material of the ring is generally 440C stainless steel, which has the properties of rust prevention and corrosion resistance. The material of the balls can be stainless steel balls or ceramic balls. Ceramic balls are usually made of Si3N4 ceramic, which has high hardness and a low thermal expansion coefficient. During high-speed rotation, it can effectively reduce the influence of centrifugal force and improve the stability and service life of the bearing.
Precision grade: The precision grade can reach ABEC-1, ABEC-3, ABEC-5, ABEC-7, etc. Among them, ABEC-7 is a higher precision grade, which can meet the high-speed and precise dental treatment requirements.
Performance parameters: This bearing features high speed, low noise and long service life. Under a pressure of 200-250 kPa, the rotational speed can reach 350,000-450,000 revolutions per minute, and the normal working life is approximately 6 months.
